Chemist location

Lamp oil is obtained by distilling Swamp tar, using the lamp oil still located in the Chemist's House in Rimmington, or Miltog's Lamps in Dorgesh-Kaan.

Note: You need to bring the Oil lampOil lantern or Bullseye lantern(empty) to hold the oil in. The oil will stay inside the lamp oil still until you use the item in your inventory on the still. You will also need to bring Swamp tar (one tar per lamp) in order to make it into Lamp Oil. Simply use the tar on the still, followed by the empty lamp, which will fill it and allow it to be lit.

It is recommended to only use the Lamp oil on the Bullseye lantern, as the lantern is the only light source that uses Lamp oil which stays lit unless the player manually extinguishes it, as it does not cause an explosion in the Lumbridge Swamp Caves, nor does it go out when players fail a shortcut around water, and the lantern is used in Tears of Guthix and Lunar Diplomacy to make other variations of itself used for the quests.
